I've mentioned one experience before. In the past 13 years, I've been at two large companies and three startups. The large companies never required seven-day work weeks on a regular basis, crunches yes (a couple of times a year), regularly no. Of the three startups: - one was in the 40-50 hour week normal expectation, no serious spikes due to the way we worked over a 2 year period. - one was 40-50 hours per week with regular (every 2-3 month spikes) - one was completely insane and expected 60+ hour weeks (it was saner pre-"coming out party", but barely). This company had no concept of planning, if things were behind, the solution was more meetings rather than cutting features. Senior management on the team was more apt to either not be around or play ping pong while engineers worked away. Technically, it was the most diverse project I ever worked on, but the most poorly run...that was a reflection on immediate management. Launch was 60+ hour weeks plus I got the fun of doing ops since I knew most of the system. That third company taught me a lot, probably most directly, the value of work life balance and, especially as a lead, pushing back on poor planning and management. My goal as an engineer has always been to deliver and provide end user delight, but that needs to be balanced with balance for myself.
